8 Claims. 1

This invention relates to spools or reels and more particularly to reels for moving picture film.

One of the objects of my invention is the provision of a reel for film in which the film may be very readily secured for winding and from which the film is readily removable without injury thereto.

Another object of this invention is the provision of a reel of the character set forth, which is simple in construction and inexpensive to manufacture.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawing which, by way of illustration, shows a preferred embodiment and the principle thereof. Other embodiments of the invention embodying the same or equivalent principle may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and a purview Of the appended claims.

In the drawing:

Fig. l is a front elevational view of a reel embodying my invention.

' Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is an enlarged sectional view taken on line 33 of Fig. 1.

Fig. 4 is an enlarged sectional view taken on line 44 of Fig. 1.

Referring to the drawing, the reel illustrated comprises two identical companion sheet metal stampings, indicated generally by the numerals 1 and l, and formed to provide flanges 8 and 8, each having a hub portion Ill and Ill. Since the companion stampings are identical in construction only one will be described, with primed reference numbers used to identify corresponding parts of the companion stamping.

In the preferred embodiment of my invention, openings 82 are stamped out of each flange to reduce weight without impairing the rigidity. Each stamping is formed with an opening I3 for receiving a spindle. Two lugs I4 and I5 are struck out of'the flange 8 and are bent out of the plane of the flanges at right angles thereto tosupport the film when the latter is wound thereon, and provide a portion of the hub structure. Projections lS-IG are provided at the ends of the lugs I4 and I5 and are adapted to be' received in registerin apertures provided in the companion stamping. The projections I6 are arranged to be peened over to secure the stampings l and I in assembled relation. As will be noted, the two lugs I4 and I5 and apertures I1 and I 8 in the stamping I are spaced radially about 90 apart, the lugs I4 and I5 being located in one half of the hub circle and the apertures I! and I8 in the other half. Two semi-circular tabs and 2|, arranged on a diametrical line and struck from the stamping l, are bent at right angles to the plane of the flange 8 and, when in juxtaposed relation to corresponding tabs such as 2|, illustrated in Fig. 2, of the companion stamping I, are arranged to provide additional platform surfaces to support the wound film.

Two tabs 23 and 24, arranged on a diametrical line, are struck out of the hub portion of the stamping 1 and are bent out of theplane of the flange 8 to provide platform portions 26 and 2'! and lips 29 and 30, respectively, with the lips lying in a plane parallel to that of the flange, and ofiset therefrom. Companion lips 29, 39', and 38, 29' of companion stampings 1 and I are arranged in juxtaposition with the lips in spaced relation.

The side flange 8 is provided with a radial slot 32 which extends from the marginal edge of the flange 8 to the hub portion I 0 and through the platform portion 21 to the lip 30. The slot 32 connects with a slot 34 provided in the lip 3Il. As viewed in Fig. 1, the slot 34 is slightly inclined upwardly with respect to the longitudinal axis of the slot 32. Another slot 35 is provided in the platform portion 26 of the opposite tab 23 and connects with a slot 3'1 in the lip 29, said slot being inclined downwardly, as viewed in Fig. 1.

As was previously noted, each of the stampings I and I is identical in construction, but in assembly the stampings are turned 180 relative to each other so that companion lips 29 and 323' and 30 and 29' are juxtaposed and are in spaced relation, as shown in Fig. 2; The slot of the platform portion 26' is in alignment, however, with the slot 32. The slots 34and 3'l of'juxtaposed lips 30 and 29', respectively, are oppositely inclined and as will be presently described, operate to retain a film end 40 therebetwee'n.

Preliminary to winding a film on the reel, the film end is grasped between the fingers at a distance substantially equal to the length of the slot 32 and is inserted sidewise therethrough' to position the fllmlwithin the plane of the side flanges 8 and 8'. The film end is then urged towards the center of the reel to cause the terminal portion of the film to enter between the oppositely inclined slots 34 and 3'! and to be deformed there- It will be seen from the foregoing, that ,an.

effective securement of the film end for winding on the reel is accomplishedfin a minimumamount of time, and with a minimumpf 'efiort'. 'In 'view of the provision of duplicate structure on each side fiange stamping, a slot isconveniently available to the user for beginning the winding of the film regardless of which side is presented to view when the reel is picked up for use.

I claim:
